HiGEM HadCM3(L30) example dataset contents

The HadCM3(L30) dataset is a 100 year dataset made up of a number of model runs. The run is split into a number of segments due to run restarts and data archiving problems. The run identifiers and the times they span are:

Run IdentifierStart (UM format)Start (yyyy-mm)End (UM format)End (yyyy-mm)
xbarep0jan2050-01q9dec2069-12
xbarqr0jan2070-02r0mar2070-03

Intially, since this is an example dataset, only the fields at the highest time resolution have been archived. Monthly mean and Seasonal mean files also exist and can be archived if requested.
